This is currently more fine grained than the other implementations; we have complete control over the tlb, so we only demap specific pages. We take advantage of the ranged tlb flush api to send one ipi for a range of pages, and due to the pm_active optimization we rarely send ipis for demaps from user pmaps. Remove now unused routines to load the tlb; this is only done once outside of the tlb fault handlers. Minor cleanups to the smp startup code. This boots multi user with both cpus active on a dual ultra 60 and on a dual ultra 2.
